The Screening Process In Platinum Mining

[Ganoksin] Platinum Jewelry Making - Maximizing Refining Returns for Platinum. During the screening process; if oversized material is present, these materials should be returned to the customer or melted, sampled and assayed.This is due in some part to the problems associated with platinum mining operations, which have had serious affects on the market price of platinum.

How Is Platinum Extracted? - Reference

Apr 13, 2020  Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another. This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum.

Screening of Materials and Types of Screens – IspatGuru

Oct 16, 2015  The process of screening falls under two categories namely (i) screening by stratification, and (ii) screening by free fall. In the case of screening by stratification, screening is carried out by building up a material bed on a screen deck. The material gets stratified when the motion of the screen reduces the internal friction in the material.
